Miller, Mayo, Alvah E. Young, Detour, and William M. lowell, Forest Heights, Md, assignors to the United States of America as represented by the Secretary of the Navy Filed Aug. 27, E52, Ser. No. 396,744 66 Claims. (Cl. 89-45) (Granted under Title 35, US. (Code (1952), see. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

This invention relates to improvements in ammunition handling apparatus, primarily intended for use aboard ship but as readily adaptable to use at shore stations and which, conceivably, could be employed in a variety of circumstances wherein it is required to transfer load units from a supply dump to an elevated and rotating target of delivery.

Applying the following description to the primary use of the invention, the problem which it is contrived to meet is that of keeping the feeding of fixed ammunition equal to the firing rate of a rapid-firing gun. Since the latter is expected to keep up a predetermined rate of fire, it is manifest that there must not be any interruption such as can occur when the human factor is relied upon in the feeding cycle.

To the foregoing end, the rotary gun mount is relieved of the necessity of storing and carrying with it any ammunition excepting that which is about to be fired, thus reducing the moment of inertia of the gun mount to as low a value as possible and deriving from the training mechanism the highest possible quickness of response and precision.

Therefore, it is an object of the invention to provide an apparatus for transferring ammunition from an established stationary loading point to a gun feeding mechanism, which according to the instant disclosure is carried by a rotary gun mount, continuously and automatically without interruption of or slowing down the normal rate of fire of the gun.

Another object of the invention is to provide what is known as an off-mount ammunition feed, the significance of which is to segregate the ammunition supply and its delivering machinery to stationary structure beyond the perimeter of the trainable gun mount so as to minimize the load imposed on said mount.

Another object of the invention is to make the transfer mechanism in the form of several concentric ring components, each capable of rotating independently of each other and functioning as ring conveyors, their concentricity providing the easiest possible access both to the ammunition loading assemblies on the outside and to the ammunition off-takes (or gun hoist-feeders) on the inside.

Another object of the invention is to make the foregoing rotating structure in the form of at least three concentric rings, the outer and inner ones of which have shutter assemblies which demarcate the ammunition positions for the respective loading and offtake assemblies, the third or middle ring having a system of shuttles for switching ammunition from waiting positions in the shutter assembiles on the outer ring into vacant shutter assembly positions on the inner ring as such vacancies occur due to ammunition expenditure at the gun.

Another, object of the invention is to surround the gun mount and its ammunition hoist (for either single or multiple barrel gun mounts) with a number of ammunition or supply sources, all equipped to feed ammunition to the hoist, the transfer mechanism for getting the ammunition from said sources to the hoist consisting of an annular conveyor operating between the mount and the outlying supply sources, at a rate fast or slow enough to meet either the maximum or minimum rates of ammunition expenditure.

Another object of the invention is to make it a totally automatic act to transfer a round of ammunition from the loading assembly to the ammunition hoist, the chain of events which start the automatic action being the absence of a round from the ammunition entrance of said ammunition hoist.

Another object of the invention is to provide a rotary, dual, annular magazine centered on a fixed gun mount, with loaders located externally of the magazine and offtakes located internally of the magazine, the respective loaders and oiftakes delivering and receiving the ammunition in directions substantially tangential to the magazine so as to keep the rounds moving on flow lines easily conforming to the directions of rotation of the ring components of the magazine.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is a diagrammatic plan view of the ammunition transfer mechanism;

FIG. 2 is a vertical section of the complete structure, as though taken substantially on the line 2-2 of FIG. 1;

FIG. 3 is a detail plan view of the lower segment of FIG. 1, the middle ring angle frame being omitted;

FIG. 4 is a side elevation of one of the outer ring shutter assemblies, a middle ring shuttle assembly and a transfer mechanism, substantially as viewed on the plane AA of FIG. 3; I

FIG. 5 is a vertical section taken substantially on the line 5 5 of FIG. 4 but extending farther down into the the line 7 7 of FIG. 5, the rounds again being shown in plan;

FIG. 8 is a cross section taken on the line 8-8 of FIG. 5 H

FIG. 9 is a cross section taken on the line 9-9 of FIG. 10 is an enlarged view of the central portion of FIG. 3, partly in plan and partly in section, illustrating the transfer of a round from one of'the external loaders to the ring assembly; v

FIG. 11 is an enlarged plan view, parts in section, again of the central portion of FIG. 3, illustrating the transfer of a round from the ring assembly to what is known as the right hand offtake;

FIG. 11a is a detail view following FIG. 11, showing theftransfer door in open position;

FIG. 12 is a plan view of some ofthe middle ring

1. MECHANISM FOR RAPIDLY AND AUTOMATICALLY TRANSFERRING LOAD UNITS FROM A RELATIVELY STATIONARY POINT TO A TRAINABLE POINT OF DELIVERY, SAID MECHANISM COMPRISING A CONCENTRICITY OF RING ASSEMBLIES THE INDIVIDUALS OF WHICH ARE ROTATIVELY OPERATIVE ADJACENT TO THE STATIONARY POINT AND TRAINABLE POINT OF DELIVERY RESPECTIVELY TO RECEIVE LOAD UNITS FROM THE STATIONARY POINT AND TO DELIVER THEM TO SAID TRAINABLE POINT OF DELIVERY, SAID RING ASSEMBLIES INCLUDING AN OUTER RING ADJACENT SAID STATIONARY POINT, A MIDDLE RING, AND AN INNER RING, SAID MIDDLE RING BEING ROTATABLY MOUNTED BETWEEN THE OUTER RING AND THE INNER RING, AND SWITCHING MEANS CARRIED BY THE MIDDLE RING FOR AUTOMATICALLY SWITCHING LOAD UNITS FROM THE OUTER RING ACROSS THE MIDDLE RING TO THE INNER RING IN RESPONSE TO A LOAD UNIT BEING DELIVERED FROM THE INNER RING TO THE TRAINABLE POINT OF DELIVERY, SAID INNER RING BEING CONTINUOUSLY DRIVEN AT A UNIFORM SPEED RELATIVE TO THE TRAINABLE POINT OF DELIVERY, SAID OUTER RING BEING CONTINOUSLY DRIVEN AT A UNIFORM SPEED RELATIVE TO SAID STATIONARY POINT AND OPPOSITE TO THAT OF SAID INNER RING, THE ROTATION OF SAID MIDDLE RING BEING DEPENDENT UPON THE RATE AND DIRECTION OF TRAIN OF THE POINT OF DELIVERY.
